Abstrakt: A hydraulic model investigation of a proposed breakwater extension for St. Paul Harbor, St. Paul, Alaska, was conducted at a geometrically undistorted scale of 1:38.5, model to prototype. Tests were conducted for a typical cross section at the -25 ft mllw contour. Data collected included wave runup, rundown, overtopping rate, and displacement of armor stones. Maximum breaking wave conditions were used for prototype wave periods of 11, 14, and 16 sec. Breakwater cross sections tested were (a) the proposed design with a prototype crest elevation of +37.0 ft mllw and a sea-side slope of 1V:2.5H, and Cb) revisions to the proposed design with crest elevations of +30,0 ft mllw and +32.0 ft mllw and sea-side slopes of 1V:2H. The plan with a crest elevation of +32.0 ft mllw was determined to be the most economical structure that provided satisfactory stability and overtopping rates.
